Injection molding plants often encounter problems such as unstable product size or shrinkage within 48 hours during product injection molding processing. plastic molding size What should I do if there is a size deviation in injection molding?
Machinery and equipment
1. If the plasticizing capacity is insufficient, a machine with a large plasticizing capacity should be selected.
2. If the material supply is unstable, you should check whether the voltage of the machine is fluctuating, whether the components of the injection system are worn or whether there is any problem with the hydraulic valve.
Injection mold
1. There must be sufficient mold strength and rigidity, and the cavity material should be made of wear-resistant materials
2. When the dimensional accuracy requirements are very high, try not to use one-mode multi-cavity form.
3. The ejection system, pouring system and cooling system should be set reasonably to ensure stable production conditions.
plastic raw materials
1. The mixing of new material and recycled material should be consistent.
2. The drying conditions should be consistent and the particles should be uniform.
3. Fully consider the effect of shrinkage on dimensional accuracy when selecting materials
